Reaction liquid pH value detecting and adding device for lithium battery industry

Abstract

The invention relates to the technical field of chemical reaction pH value control, in particular to a reaction liquid pH value detecting and adding device for the lithium battery industry, which comprises a base, the base comprises a bottom shell, a support rod is fixed on the bottom shell, a support frame is fixedly sleeved on the support rod, a pH detector is arranged at the front end in the bottom shell, and solution tanks are movably clamped at two ends of the support frame. Liquid dropping peristaltic pumps are arranged on the two sides of the support rod, each liquid dropping peristaltic pump comprises a hose, one end of each hose is connected to the adjacent solution tank, and the other end of each hose is connected with a liquid adding pipe. According to the invention, the pH value of the reaction liquid can be detected in real time, meanwhile, the acid / alkali neutralization liquid is automatically added into the reaction liquid to maintain the stable pH value, the adjusting process is rapid and accurate, the reaction liquid keeps the optimal reaction effect all the time, and then the stability of the product performance is ensured.

Description

technical field [0001] The invention relates to the technical field of chemical reaction acidity and alkalinity control, in particular to a reaction liquid pH value detection and addition device used in the lithium battery industry. Background technique [0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive / negative electrode materials and use non-aqueous electrolyte solutions. Lithium-ion battery cathode ternary materials are the focus of current research. During the preparation process, a continuous feeding reaction process is required to improve production efficiency. However, during the continuous feeding reaction process, pH fluctuations are prone to occur, which affects the efficiency of the reaction. However, the manual adjustment of pH is not fast enough and the accuracy is low, which leads to unstable product performance. Contents of the invention [0003] The object of the present invention is to provide a reactio...
